Answer Key : (d) -

(d)

As only the gravity force is acting on the system, the centre of mass of the system follows a parabolic path

At ,

Let coordinates of the second piece, i.e., 6 kg piece be

Then

Negative value of shows that the second piece collides the ground before

The effect of todays radioactive fall out will probably be more harmful to children of future generation than to children now living because
1)	Infants are more susceptible to radiations
2)	Susceptibility to radiation increase with age
3)	Mutated genes are frequently recessive
4)	Contamination of milk supply is not cummulative
